简介:目的:研究干眼症的病因,为干眼症的诊断提供依据,减少误诊的发生。方法:回顾性分析83例确诊为干眼症的患者的发病原因,并分析其中16例发生误诊的病例。诊断方法为依据干眼症症状、泪膜稳定性下降、泪液分泌减少及眼表损害等表现,并按一定的诊断步骤进行。结果:干眼症患者83例中最常见的原因是视屏终端综合征24例(29%)、慢性睑缘炎12例(14%)、干燥综合症12例(14%)。有10例误诊为慢性结膜炎,有2例误诊为病毒性角膜炎,另有4例干眼症的病因诊断错误。结论:干眼症的发病原因虽不是诊断干眼症的必备条件,但认识并积极寻找干眼症的病因可以为诊断提供依据,同时也可减少误诊的发生。

简介:目的探讨化脓性泪小管炎的诊断及治疗方法。方法回顾性分析2008年1月至2015年6月在我院收治的28例化脓性泪小管炎确诊患者。把他们分为4组。第1组单纯泪小管炎,冲洗泪道有液体进入鼻口腔。第2组泪小管炎合并泪小管阻塞。第3组泪小管炎合并慢性泪囊炎但不合并泪小管阻塞。第4组泪小管炎合并慢性泪囊炎及泪小管阻塞。所有组用聚维酮碘结膜囊冲洗及泪小管灌洗,同时泪小管中用妥布霉素冲洗并注入盐酸左氧氟沙星眼用凝胶,眼局部给予妥布霉素地塞米松滴眼液点眼,脓性分泌物减轻后第1组给予保守治疗;第2组给予泪小管切开术。第3组给予泪囊鼻腔吻合术。第4组给予泪囊鼻腔吻合+泪小管切开术,术后同术前保守治疗。结果所有组泪小管炎全部治愈。但第2及第4组各有1例泪小管阻塞。结论聚维酮碘结膜囊冲洗及泪小管灌洗,泪小管中用妥布霉素冲洗并注入盐酸左氧氟沙星眼用凝胶,眼局部给予妥布霉素地塞米松滴眼液点眼,或在此基础上合并泪小管切开和/或泪囊鼻腔吻合术,简单方便,疗效确切。
简介:目的探讨桥小脑角疾病的相位平衡快速梯度回波(Balance-FastFieldEcho,B-FFE)序列MRI影像学特点,评价B-FFE序列对桥小脑角疾病的诊断价值.方法应用B-FFE序列对136例桥小脑角病变者(三叉神经痛131例、半面痉挛5例)进行MRI检查,观察桥小脑角神经、血管、肿瘤显像情况,并与手术中资料进行比较.结果131例三叉神经痛患者中,117例为原发性三叉神经痛,MRI显示有血管压迫者102例,术中证实有血管压迫者95例,行显微血管减压+神经梳理术;14例为继发性三叉神经痛,均为桥小脑角占位性病变,术后病理证实7例为胆脂瘤,2例为听神经瘤,5例为脑膜瘤;5例半面痉挛患者MRI显示有血管压迫,术中证实有血管压迫,并予以血管减压.结论B-FFE序列MRI成像能清楚显示桥小脑角区三叉神经、面神经与血管的关系及是否有占位性病变,对诊断、术前评估和指导治疗有重要意义.
